Subject: [PATCH v3 04/24] soc/fsl/qbman: use ioremap_cache() instead of ioremap_prot(0)
Date: Tue, 9 Oct 2018 13:51:39 +0000 (UTC) [thread overview]
Message-ID: <841b980a6f1b3e9a9d3c20c5da39a88292033dbe.1539092111.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1539092111.git.christophe.leroy@c-s.fr>
ioremap_prot() with flag set to 0 relies on a hack in
__ioremap_caller() which adds PAGE_KERNEL flags when the
handed flags don't look like a valid set of flags
(ie don't include _PAGE_PRESENT)
The intention being to map cached memory, use ioremap_cache() instead.
